When oil prices fluctuate globally, the BAF is imposed to basic ocean freight to stabilize the cost of freight. BAF has derived from the term bunker (fuel storage containers). Such surcharge is added up on the ocean freight by shipping companies to supplement fuel factor costs and termed as BAF.
Popular Answers. 1  A phase, or state of matter, is a domain within a many-body system within which relevant physical properties are uniform. Relevant properties may include chemical composition, stoichiometry, and density, which do not reflect how the components are arranged in space.
Phase transition. The term phase transition (or phase change) is most commonly used to describe transitions between solid, liquid and gaseous states of matter, and, in rare cases, plasma (physics). A phase of a thermodynamic system and the states of matter have uniform physical properties. During a phase transition of a given medium, certain properties of the medium change, often discontinuously, as a result of the change of some external condition, such as temperature, pressure, or others.
